Description: POE::Component::Client::Keepalive creates and manages connections for other components. It maintains a cache of kept-alive connections for quick reuse. It is written specifically for clients that can benefit from kept-alive connections, such as HTTP clients. Using it for one-shot connections would probably be silly.

Description: Pastebot is a pastebin server and IRC bot in one program. Users submit short pieces of text to the web server, and the IRC bot announces them in IRC. Pastebot may have invented the pastebin. As of the time of this writing, Wikipedia’s Pastebin article cites Pastebot as the earliest recorded pastebin.
